Modified Sauve-Kapandji Procedure Using Iliac Bone Graft for Giant Cell Tumor of the Distal Ulna: Stabilizing With Two-Screw Fixation

Case: We describe a 33-year-old man who had a giant cell tumor in the ulnar head treated with wide resection and reconstructed using the modified Sauve-Kapandji procedure with an iliac crest bone graft as ulnar support. Conclusions: Due to the destructive nature of the tumor and the important role played by the ulnar head in the distal radioulnar joint (DRUJ), treatment of the giant cell tumor in the distal ulna is a challenge. The modified Sauve-Kapandji procedure is an effective technique to restore DRUJ function, which is performed as an ulnar support arthroplasty. Using an iliac crest bone graft as ulnar support in reconstruction surgery could be a practical method after the ulnar head has been resected.
